(CNN) – Donald Trump is looking to steady his campaign after several rocky days by taking aim at Hillary Clinton.

Donald Trump: “Hillary Clinton can never be trusted with national security.”

Attacking the Obama administration’s $400 million payment to Iran. Still repeating the false claim that he saw video of the transfer taking place.

Donald Trump: “A tape was made, right? You saw that with the airplane coming in – nice plane – and the airplane coming in and the money coming off, I guess, right? That was given to us – it has to be – by the Iranians, and you know why the tape was given to us? They want to embarrass our country and they want to embarrass our president.”

This as the GOP nominee tries to reassure voters and republican leaders wary of his recent series of missteps that his campaign is moving in the right direction. Helping him make the case a big July fundraising haul.

Donald Trump: “$80 or $82 million this month. Raising a lot of money for Republican Party. Small contributions $61 each.”

Trump’s rhetoric catching up with his running mate on the trail. With mike pence today being challenged by an 11-year-old boy on whether his role is to tone down Trump’s words and policies.

Mike Pence: “Sometimes things don’t always come out like you mean, and Donald Trump and I are absolutely determined to work together, we have different styles. But I would tell you differences in style should never be confused with differences in conviction.”

Pence and Trump do have a split when it comes to support for house speaker Paul Ryan with pence endorsing Ryan Wednesday. A day after Trump said he wasn’t ready to do so. Ryan Thursday shrugged off Trump’s hesitancy.

Paul Ryan: “The only endorsements I want are those of my own employers here in the first congressional district.”

Ryan also refused to commit to back Trump in the future.

Paul Ryan: “None of these things are ever blank checks that goes with any situation in any kind of race.”

While he is backing Ryan, Pence Thursday refused to endorse two other republicans Trump has criticized John McCain and Kelly Ayotte, both seeking reelection to the senate this year.

Mike Pence: “I look forward to supporting Republican candidates in the days and weeks ahead all over the country, and so does Donald Trump.”

There is also new evidence of frustration with Trump’s candidacy among republicans. Colorado congressman Mike Coffman, who is facing a tough re-election, released a TV ad vowing to take on Trump.

Mike Coffman: “So if Donald Trump is president, I’ll stand up to him.

However party unity is not the only concern for the Trump campaign. A fresh round of poll numbers today show Hillary Clinton leading Donald Trump in three key states: up 9 points in Michigan. 13 points in Pennsylvania, and 15 points in New Hampshire.

Where that deficit could also spell trouble for republican senator Kelly Ayotte’s re-election bid. Manafort says the dip is no surprise. We had a bounce, we knew that the Democrats would have a bounce.”
